Double Slit Wave-Particle Duality Model

written by
Wolfgang Christian

The Double Slit Wave-Particle Duality Model demonstrates how matter and light display both wave- and particle-like properties in single and double slit experiments. The simulation shows a detector screen placed behind an aperture with one or two open slits. Particles (electrons or photons) pass through the experiment one at a time and their impact is recorded on the screen. Although it is at first difficult to discern a pattern, a diffraction (interference) pattern eventually emerges suggesting that each particle is interfering with itself. The particle seems be going through both slits as if it were a wave but is detected (observed) at only one location as if were a particle. The particle is interfering with itself as if it were simultaneously passing through both slits.

The Double Slit Wave-Particle Duality Model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double click the ejs_qm_DoubleSlitWaveParticleDuality.jar file to run the program if Java is installed.
